我正在尝试在 Ubuntu 14.10 上安装 OpenCV，但我一次又一次地面临这个错误:(

    /usr/bin/ld: /usr/local/lib/libavcodec.a(avpacket.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC

请在遇到错误之前提供命令历史记录。

如果调用make是错误发生之前的最后一件事，您可以尝试调用make CFLAGS="-fPIC"。

迟到了，但问题是 FFMPEG 不是用与位置无关的代码编译的。转到您的 FFMPEG 目录并执行

./configure --enable-nonfree --enable-pic --enable-shared

然后重做make，make install步骤，并重新构建opencv。
